When it comes to using SASS, there are multiple ways of setting up your workspace.
Some people prefer to use command line tools (probably Linux people) and others prefer to use GUI applications. I'll cover both.
Command Line Tools
The 'Install SASS' page at sass-lang.com covers this quite well. ...

Elm has a special syntax for lambda expressions or anonymous functions:
\arguments -> returnedValue
For example, as seen in List.filter:
> List.filter (\num -> num > 1) [1,2,3]
[2,3] : List number
More to the depth, a backward slash, \, is used to mark the beginning of lambda ex...

CLP(FD) constraints (Finite Domains) implement arithmetic over integers. They are available in all serious Prolog implementations.
There are two major use cases of CLP(FD) constraints:
Declarative integer arithmetic

Packages are bundles of classes. Every class must be declared within a package using the package statement. The package statement is followed by the name of your package, or followed by nothing in the case of adding classes to the top-level package. Sub-packages are created using dot (.) delimitatio...
Import the numpy module to use any part of it.
import numpy as np
Most examples will use np as shorthand for numpy. Assume "np" means "numpy" in code examples.
x = np.array([1,2,3,4])
A comment is marked by an apostrophe ('), and ignored when the code executes. Comments help explain your code to future readers, including yourself.
Since all lines starting with a comment are ignored, they can also be used to prevent code from executing (while you debug or refactor). Placing an ap...

The numpy.reshape (same as numpy.ndarray.reshape) method returns an array of the same total size, but in a new shape:
print(np.arange(10).reshape((2, 5)))
# [[0 1 2 3 4]
# [5 6 7 8 9]]
It returns a new array, and doesn't operate in place:
a = np.arange(12)
a.reshape((3, 4))
print(a)

Draw samples from a normal (gaussian) distribution
# Generate 5 random numbers from a standard normal distribution
# (mean = 0, standard deviation = 1)
np.random.randn(5)
# Out: array([-0.84423086, 0.70564081, -0.39878617, -0.82719653, -0.4157447 ])
# This result can also be achieved with t...
